6 Strategies to Shorten the Introduction Section of Your Research Paper
Fitting your research within a journal’s word-count requirements can be a struggle, particularly when it comes to the introduction. It can feel impossible to cut this section down to the required length when everything seems relevant.
In this post, I’ll show you how to turn that seemingly impossible task into an achievable one.
This article runs through the six most effective strategies for reducing the word count of research papers, which I’ve learned from working as an editor over the last decade.
The strategies fall into two broad categories:
Cutting information
Deleting irrelevant material
Removing minor details about previous studies
Avoiding unnecessary explanations
Compressing language
Summarizing overly detailed explanations
Combining sentences
Writing more concise sentences
Let’s look at each of these in more detail.
Cutting Information
It’s best to first look for sentences that can be cut before doing sentence-level revisions. You don’t want to spend minutes rewording a sentence only to delete that sentence later.
Delete material that isn’t related to the research objective.
As mentioned in this guide to writing the introduction of a research paper, the whole point of this section is to show readers why your research objective was worth exploring.
With that in mind, not only is cutting unnecessary information an effective way to shorten your introduction, but it will also make the section more cohesive.
For example, imagine someone is writing a paper with the following research objective:
This study aimed to determine whether the availability of prey influences the amount of time that wolf spiders spend searching for and capturing food using different methods in grasslands in central Minnesota.*
The author might include this sentence in their introduction:
Wolf spiders employ a variety of hunting strategies, ranging from remaining stationary and waiting for prey to actively searching for and pursuing prey, which varies depending on the type of prey they encounter, with common prey including ants, crickets, and beetles.
But if "type of prey" isn’t a variable in the study, then the spider's most common types of prey don’t need to be mentioned. The author could cut the last 22 words from the sentence and simply say:
Wolf spiders employ a variety of hunting strategies, ranging from remaining stationary and waiting for prey to actively searching for and pursuing prey.
In addition to shortening the text, this revision avoids misleading readers into thinking that type of prey is an important factor in this study.
Remove minor details about previous studies.
Each time you mention a previous study in your introduction, it’s worth checking whether you’ve provided any unnecessary details.
Using the same fabricated paper on wolf spiders’ hunting behavior, you would be able to trim the sentence below quite a lot:
In a study conducted over a twelve-month period, Author A et al. (2026) found that prey availability was significantly positively correlated with how long wolf spiders spent hunting prey, with time spent hunting peaking at 3.8 hours per day in November, when prey were more abundant, and reaching its lowest level of 1.6 hours per day in July, when prey were more scarce.
If we keep only the critical information, we can cut 43 words:
Author A et al. (2026) found that prey availability was positively correlated with how long wolf spiders spent hunting prey.
Remember, if readers want the full details, they can always find the original article through your list of references.
Don’t explain what your readers probably already know.
When trying to shorten your introduction, it can be useful to imagine you’re writing for your peers rather than a general audience.
This allows you to remove text explaining things that many of your readers will already understand.
Take a look at this sentence:
Because wolf spiders are active hunters, meaning they actively search for and pursue their prey rather than relying on webs to capture them, researchers have suggested that they give up relatively quickly when hunting in patches with few prey (Author B et al., 2023; Author C et al., 2022).
It’s a safe assumption that most readers interested in this research will know what “active hunting” is. So, we can eliminate the 17-word definition:
Because wolf spiders are active hunters, researchers have suggested that they give up relatively quickly when hunting in patches with few prey (Author B et al., 2023; Author C et al., 2022).
Compressing Language
Individually, these changes don’t always lead to drastic word-count reductions (though they sometimes can). But over an entire introduction section, they can add up.
Summarize details.
If the overall point you’re making is more important than the supporting details or examples, you can shorten your introduction by summarizing what the details show.
For example, if the author of our fictional study wanted to highlight that previous findings are inconsistent, they could say:
The idea that greater prey availability is associated with longer foraging times in wolf spiders is supported by Author D et al. (2024), who showed that wolf spiders living in grasslands spent more time hunting in areas where prey were abundant. Similarly, Author E et al. (2020) showed that wolf spiders remained longer in areas with higher prey availability, both when hunting and when idle. However, Author F et al. (2025) showed that wolf spiders spent more time hunting when prey were extremely scarce than when prey were abundant.
The reader doesn't need all those details to understand that previous results are mixed. So, to shorten the word count, the author can simply tell readers in plain language that previous findings are inconsistent:
While Author D et al. (2024) and Author E et al. (2020) support the idea that greater prey availability is associated with longer foraging times in wolf spiders, Author F et al.’s (2025) work indicates the opposite pattern.
Combine ideas that can be expressed in one sentence.
Another good way to reduce your word count is to look for places where two sentences work together to make one point and combine them into a single sentence.
For example, an author might write:
Wolf spiders consume a variety of small arthropods. Their diet commonly includes crickets, beetles, and flies.
Since these ideas are very closely related, the information could be given together, which lets you remove the first three words of the second sentence:
Wolf spiders consume a variety of small arthropods, including crickets, beetles, and flies.
Replace wordy constructions with concise alternatives.
This is something I do as part of Magnum Academic Editing’s Full Language Editing Package. From experience, I know that making these sentence-level changes often reduces a paper's word count by 5–10%.
There are a great many ways to avoid wordiness at the sentence level. Below are some of the most common ones I use when editing.
Replace noun phrases with -ings.
Whenever you see the pattern “the [noun] of X,” there’s a good chance you can trim a couple of words by replacing this noun phrase with the -ing form of a verb.
Example
Instead of:
The construction of wolf-spider burrows involves several stages.
Write:
Constructing wolf-spider burrows involves several stages.
Let your citations carry some of the load.
You don’t need to tell readers that you’re referring to a study when you provide a citation; they will assume this is the case unless told otherwise. This gives you some opportunities to cut a few words from your introduction here and there.
Example
Instead of:
In a study conducted by Author A et al. (2020), it was found that wolf spiders spent more time hunting when prey was abundant.
Write:
Author A et al. (2020) found that wolf spiders spent more time hunting when prey was abundant.
Remove empty phrases.
Empty phrases are referred to as “empty” because they do not add to or change the meaning of a sentence. They just sit there, taking up space.
Example
Instead of:
It is worth noting that wolf spiders are more active during warmer months.
Write:
Wolf spiders are more active during warmer months.
Other common empty phrases to watch for in your writing include:
it should be mentioned that
it is worth stating that
it should be pointed out that
it is known that
it can be observed that
Avoid starting sentences with “there are.”
The words "there are" can often be cut when they start a sentence.
Example
Instead of:
There are many spider species that hunt primarily at night.
Say:
Many spider species hunt primarily at night.
Replace verb phrases with single verbs.
If one word can do the job of a phrase, use that word.
Example
Instead of:
Prey scarcity has an influence on hunting behavior.
Say:
Prey scarcity influences hunting behavior.
